Attackers can supply a malicious .md2 file whose numFrames and numVertices values wrap the 32-bit size check, causing heap out-of-bounds reads that crash applications or expose adjacent heap memory.","epss":{"date":"2026-11-02","percentile":0.02979,"score":0.00135},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/assimp/assimp/issues/6929"}],"kev":null,"metrics":[{"score":6.9,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":6.1,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"}],"modifiedAt":1793709579458,"publishedAt":1793152997365,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/assimp/assimp/issues/6929"},{"source":"CNA: VulnCheck","tags":["patch","issue-tracking"],"url":"https://github.com/assimp/assimp/pull/6963"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/assimp/assimp/commit/7dbc85d9218fae017d4fad70269e7569f7b0c870"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/assimp/assimp/blob/v6.0.5/code/AssetLib/MD2/MD2Loader.cpp#L171-L176"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/assimp/assimp"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/assimp-through-6.0.5-heap-out-of-bounds-read-via-md2-importer-integer-overflow"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/assimp/assimp/issues/6929"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
